change users style

I was thinking of this would be fun
Have a option where a user could use there points to change another members sytle(right now we have one style) I want to create a hard to see style but that user that gets his style changed would have the option to use his points to get (out of Jail) style and be able to see who sent him to the crazy style.
I would also like this to have a time limit of say a week to be in that style.
Hope this makes sense
